UCUP-ZJ M. Minimum Element Problem
题意 给定一个位置x,求在$p_x$分别取1-n的所有情况下,对应笛卡尔树不同的排列个数。 题解 先不考虑$p_x$,列出转移式,发现是卡特兰数。 进一步地,可以把排列对应笛卡尔树意义下的不同构数,和二叉树不同构数等价联系起来:因为对于任何一个二叉树,按照中序遍历在上面填1-n,就可以唯一确定一个排 ......

Linux命令su、sudo、sudo su、sudo -i使用和区别
sudo 与 su 两个命令的最大区别是: sudo 命令需要输入当前用户的密码,su 命令需要输入 root 用户的密码。另外一个区别是其默认行为,sudo 命令只允许使用提升的权限运行单个命令,而 su 命令会启动一个新的 shell,同时允许使用 root 权限运行尽可能多的命令,直到明确退出 ......
Paper Reading: XRRF — An eXplainable Reasonably Randomised Forest algorithm for classification and regression problems
本文提出了一种 XRRF 算法,它通过执行本文提出的 SGFL 和 RRF 算法来得到可解释性、准确性和可解释性之间的权衡。随后引入了基于决策路径特征提取的方法,根据具体的应用解释模型的输出。其中 SGFL 能确定有助于模型准确性的特征,同时保持特征关系的可靠性。RRF 算法则通过利用所提出的改进随... ......
